UNITED STATES PATENT QEETCE LUTHER E. BURDIN, OF PARIS, KENTUCKY.

IMPROVEMENT IN SUBSOlL-PULVERIZING ATTACHMENTS FOR FLOWS.

Specification forming partof-Letters Patent No. 108,002, dated October 4, 1870.

To all whom it mayv concern! Be it known that I, LUTHER E. BUnnrN, of Paris, in the county ot' Bourbon and State of Kentucky, have invented a newv and Improved Subsoil-Fulverizing Attachment for Flows; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this speciiicaton, in which- Figure 1 is a perspective view, a portion of the mold-board ot' the plow being removed to reveal the form and application of the subsoil attachment. Fig. 2 is a sectional view of the attachment; and Fig. 3, a perspective View of the same.

The object ot' this invention is to provide for public use a simple, cheap, and edective instrument which can be readily attached to a plow, and conveniently operated therewith, and which will, at the saine time, eiectually pulverize the subsoil. This object is accomplished by the use ot' a simple apparatus, consisting of a triangular blade, a a', provided with sharp pulverizing teeth c c, and con nected tothe rear end of the plow-beam P or a block, B, attached thereto by means of a standard, s, and adjusting-strap u.

A brace, b, may be employed to strengthen the connection between lthe standard and blade, and a draft-rod, r, may extend from the standard to a bolt or staple on the rear side of the mold-board, or wherever may be most convenient, according to the formvot plow employed.

The draft-rod may be fastened to the stand ard or brace in any suitable manner; or aloop maybe made at its rear end, through which the standard may extend, as shown in the drawing. i

, The two side pieces, a a, of the triangular blade incline downward from the rear to the front edge, the Alatter edge being made sharp andcutting. These pieces are connected by a cross-piece, a', near their rear end, which is, likewise, a euttin g-bladc, having its front edge incl Ld downward.

The cutters or pulverizing-teeth c c are attached to the rear piece, a', in any suitable manner, and curve upward and backward, as

shown in the drawing. There may be as many vof these teeth as may be thought desirable to use in any particular soil, andthey may be so attached that they, or any ot' them, can be removed or changed in position or inclination. They may, it' preferred, be attached to the side pieces or to other cross-pieces in front ot' the one shown in the drawing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The snbsoil-pulverizing attachment herein described, consisting,essentially, ot the parts a a', e c, s, and d, when constructed to operate substantially in the manner and for the purpose described. Y

LUTHER E. BUItDIN.
